I've been reading Grid Control Performance Best Practices Documentation and I noticed there is a Minimum bandwidth requirement between the management agent and the management server. It is said there must be minimum 300KBps/s between the two.

I would like to know if you have any knowledge and experience of the actual bandwidth used between the two. Typically, agents will be located on our customer network and the management server on ours. My concern is that the traffic between Agent and server could be a problem since our network link between us and ours clients is often kind of light.
